IMPRovsD 'onora-PRESS.

i `Schedule referredto` in these Letters Patent and making part of the s'ame.

'Be it known tliatweGHAnLEs il. WESTON and JOHN Daams, of ,I lowell,` in Vthe county of Middlesex and in the"State `of lyassachusettsilave invented ce`r- `-tainnewandusefulImprovements in Cloth-Presses;

and do hereby .declare "that die` following isa full,

. clear, and` exact description thereof, reference being had to the accompanying drawings and to the letters .l 'of` reference marked'thereonjmaking a pal-.tof this wspecfication. i i

` i Our invention relntesto thatclass of presses known as'stean1 clothepresscs, and `consists in the coni vstruction andarrangement of .the parts thereof, as

will be morefullyhereinafter described. t

In 'orderto enable othe-rs` skilled in `the art vto which ourtinveiltion appertains to make and use the saine, we willnowproceed to describelits constructionv Vand operation, `referring to the annexed drawings,

Figure 1 is a sidevimv, and

Figure 2 is alhorizontalsection ofour` press.

. In theaccoinpanying drawings we have not deemed it necessary to'repre'sent any more of a steam clothpress. than what'is requisite for `a full understanding ofthe case. n 1

A represents" the top, and B the .bottom -or base of `the press, connected by means of\fdi 1. e orne1`}jiosts,-( (l, providedwith shoulders a afneznthcir ends, against Awhich the top andbottom rest, they being secured by nuts, the nutsl) D, under the bottom, forming the feet upon which the press rests. Or, in place of the` i nnt,yit may be a welded collarcombined with afoot.

. Two of the posts,-(l O,` a re provided with longitudinal grooves n n, as seenin ig.',2,'in which'grooves lugs or projections on the plates tit, so as to guide them in their upward and downward movement.

In two small standards, E E, n the'base B, a horizontal worm-shaft, G, has its bearings, said worms l "gearing with two cog-wheels, H H, provided with tel" `male screws in the. center, through. which pass the vertical screws I I, supporting the lower plate J, so that by turning theworm-shaft in either directions said plate is either raised or lowered. l

' 0n the shaft G, outside of the press', is placed a sleeve, K, which passes `through a. standard, L, atg

Vtaohed in "any suitable manner to the sideof the base' Bforming the bearing for thesarne.4 This sleeve is,

on its inner endfprovided with a pulley, a, the outer circumferenceof which is beveled, as shown itfg, 2,

fromthc center inward toward the edges. g On each side of the pulley c is placed afloose pulley, b, one on the shaft G, and the other on the sleeve K. rlhese pulleys b b are hollow on the sides facing the pulley a, so that they can inclose the edge of said I pulley and bear tightly against the same.

On the sleeve K, outside of the standard L, aresef cured two collars, d d, a suitable .distance apart, between which collars a loose lever, M, is placed, the lower end of saidl iever being pivoted in anrarm, e,

extending from, thestandard- L. By the use of this levcr the Vsleeve Ii may be movedso as to bring the pulley o" in contact witheither one of the pulleys b,

andsaid pulleys being conneetedlwith the epgine, one

by a straight or open, and the other. bya cross-belt,-

so"I that the` worm-shaft can readily be moved or turned in either directionto raise or lower the plat-es.` )sleeve K is provided on `its .inside with a feather The which fits in a longitudinal groove on the shaft, and thus the sleeve' may be moved endwise on the shaft,

bnt cannot revolve without also revolving the shaft.`

In the base B of the press are tivo bale-boxes, provided'with circular recesses, in which are placed a series of balls, i i, upon which screw-wheels H H rest; The balls i. 'i are of two sizes, being placedalternately a large and a sn all ball, which makes less friction than there would be it' the balls were all of one size, as it `will readily be seen that by having every other ball smaller it rolls, and does not. rnb as it would if all of one size. i

\Ve may, however, use balls all of one size, as well as cones in place of the balls, which would answer the same purpose. The balls may be placed either inside or outsideof the ball-box.

Having thus fully described our invention,

What we claim as new, and desire to secure by Let- I ters Patent, isy 1. lhe combination of the grooved standards C, plate J ,provided with end lugs a; and sockets y, the

screwI, and disks U,'whe'n these parts are con# s trncted substantially as described, and arrangedto operate as and fo1-the purpose specified. a

2.`The arrangement of the screws I, caps H, pro

vided with exterior gear-balls orcones t', wenn-shaft G, and operating pulleys a b b, all substantially as set forth. v In testimony' that we claim the foregoing, we have hereunto set our hands this-21st`day of March, 187.0;
